 Motor performance | |
Lots of pcb mill folks are using 5V motors at 12V (or more). This is 2.4 times rated voltage. The rationale is that the higher voltage produces a more rapid dv/dt (voltage slew rate), which translates into more ipm at the cutting tool.
I plan on using 1.3V motors (because I have them) and driving them at 5V. This is a 3.8 multiple and so I expect to see better speed at the tool too.
Is anyone else using these low impedance motors?
What kind of performance (ipm for want of a better metric) are you seeing?
